I illustrate my invention in the accompanying drawin which, with the letters of reference mar ed thereon, forma part of this application and in' which I` have illustrated a perspective view of the seesaw.

Reference now being had to the details of the drawings by letters:

A designates t-he base of the device, fron-14 which standards B project, having oppositely disposed perforations C for the re rods D. Beams,'designated` ception of the respectively b letters E and F are provided with recesses upon the underedges thereof which are adapted` to receive the rods D upon which the beams are fulcrumed. It will 'be noted that there is a plurality of recesses in the under surfaces of the'beams in order to balance the weights u n the beams. beam F and carries pivotal which the bars I are pivot ins I upon Plates N are pivotally mounted upon pins N carried at the extreme ends of the beam E and car the seats O. Links R are pivotally connec at their outer ends to the pivotal pins. R

which are connected to the plates N, and at 'as at S, and S design their inner ends are pivota ly connected to the bars I through the medium of the pins T. The portions of the beam F which project beyond oroutside the bars I are contracted,

atehandles which project from the opposite faces ofthe contracted ends.

The beam E is' longer t an the Bdy the provision of a seesaw, made in accor ance with my invention, it will be noted that the beams may be `easily and quickly adjusted, in order to balance dierent weights upon the seats and, the person using the seesaw may be held, in place by taking hold of the handles S.

What I claim to be new 'isz 1.- A see-saw comprising a base, havin standards spaced apart and provided witg apertures, rods mounted in oppositely disposed apertures in said standards, beams, one mounted above the other, the lower beam projecting beyond the ends of the upr beam, the under surfaces of the beams ing recessed to receive said rods, 'seats pivotally su ported upon the projecting portions of t e lower beam, and having pivotal bar and link connections with the upper beam. v

2. A see-saw comprising a base, having Vstandards spaced apart and provided with.

apertures, rods mounted in oppositely disother, the lower beam projecting beyond the ends of the upper beam, the under surfaces of the beams bein recessed 'to receive said rods, bars .pivota connecting the two beams, the lower ends of the bars projecting below the lower beam, plates pivoted. to the projecting ends of the lower beams, and seats fixed to said platesglinks pivotally connecting the lower ends of said plates with the lower ends' of said bars, and handles upon the upper bar.

In ytestimony whereof I hereunto aflix my signature in presence of two witnesses.
